Systems, methods and user interface for graphical configuration for roof mounts

ABSTRACT

Systems, methods and user interfaces for graphical configuration for ballasted roof mounts of non-rectangular solar arrays. A graphical interface may be provided to allow a user to view a roof grid, and place solar modules within the roof grid where desired, to account for various obstacles on a roof, to create a non-rectangular solar array. Using the layout of the array and various site parameters (building height, wind speed, etc.) and solar module parameters (wide, length, thickness, etc.), the system may calculate a complete bill of materials, customer pricing, ballasting requirements and overall roof loads for a complete solar project.

BACKGROUND

Designing the racking components of a photovoltaic solar system can be a time-consuming process. Several racking manufacturers have developed software that automates steps of this process for rectangular solar arrays. For example, Unirac has created a SolarMount configurator which asks a user to input the number of module rows and columns that define a rectangular array and input the number of arrays, with the assumption that each array is the same shape. Thus, for ground arrays and penetrating roof mount systems, where array shapes may be rectangular in nature, the systems may model and define the number of rows and columns for each array.

For ballasted roof mount systems, non-rectangular arrays may need to be modeled and configured. Thus, there exists a need for systems, methods and user interfaces for configuration for ballasted roof mounts of non-rectangular solar arrays.

SUMMARY

The invention provides systems, methods and user interfaces for graphical configuration for ballasted roof mounts of non-rectangular solar arrays. Various aspects of the invention described herein may be applied to any of the particular applications set forth below.

DETAILED DESCRIPTION

In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the invention. However it will be understood by those of ordinary skill in the art that the invention may be practiced without these specific details. In other instances, well-known methods, procedures, components and circuits have not been described in detail so as not to obscure the invention. Various modifications to the described embodiments will be apparent to those with skill in the art, and the general principles defined herein may be applied to other embodiments. The invention is not intended to be limited to the particular embodiments shown and described.

For ballasted roof mount systems, non-rectangular arrays may need to be modeled and configured. Ballasted systems do not necessarily exhibit the same type of regularity as other systems. For example, two modules in the interior of a large ballasted roof array might require different amounts of weight. Engineering constraints for each module of a ballasted roof mount system may depend on the other modules in the system, rather than global values for the whole array.

When trying to configure a ballasted roof mount system, one approach is to decompose it into logical sections which are typically regular geometric shapes (often rectangular). Once the array has been broken down into logical sections, the weight necessary to hold down a module to ensure that the system does not move or lift up given expected wind and other loads may be calculated based on the modules position in the section. For example, modules that have no other modules on their high side (or Northern Modules as further described below) require the most weight. Modules with no other modules attached to their low sides (or Southern Modules as further described below) require the least weight. The remaining modules require an intermediate amount.

In addition, modules can also distribute load to the other modules and racking that are attached to their rising sides (sides between the high side and low side, which may be called “east” and “west” sides). When stiffening beams are used to connect six or more modules, ballast requirements may be reduced. Thus, the greater amount of load they can distribute, the less weight they need placed on the trays to which they are directly attached; as a result, any rows in a section that include fewer than six modules attached directly in the east to west direction may be treated as a special case.

Further, roof mounted systems may also have gaps between modules to avoid collisions with things that protrude from the roof (pipes, HVAC, exists, or other obstacles). Various obstacles may be handled by imposing rules that ensure that sections start and stop around these gaps such that they are not included in a section, however, it may be difficult and time consuming to decompose an array into sections that do not violate any rules, and may often result in sections that need to be treated as special cases.

Referring to FIG. 1, a graphical representation of a roof layout may be provided to assist an operator with defining module placements in an overall array. The operator may provide certain dimensions for the roof grid (e.g., by specifying a width 101, height 102, etc.). The roof grid 103 may be formed by creating potential module placements 104, 105, 106, etc. depending on the type of solar modules which are selected for placement. The operator may determine and provide the work area size and module dimensions and the system, as a result, may display a grid that represents all of the possible locations where a module could be placed. Alternatively, the system may provide a default sized grid (e.g. 10×10) and allow the user to add columns and rows when needed. Each module box may be clicked “on” or “off,” where “on” represents that the operator would like to place a module in the position and “off” represents that no module is to be placed in the particular position.

Referring to FIG. 2, the module boxes may be clicked “on” (for example, 201) or “off” (for example, 202) one at a time, allowing the operator to define desired module placement locations. Thus, the clickable grid provides a mechanism for the user to click “on” a cell in the grid to make a module visible (or click “off” to make it go away). The individual selection tool 203 allows the operator to click module boxes individually. A module box that is clicked once will be turned “on” and may change color, for example. If the same module box is clicked again, then the module box may be turned “off” and restored to the original state. The boxes may be clicked on and off using a mouse, touch screen or any other device. This graphical input method may provide a faster and more accurate mechanism for describing the user's desired array configuration than other approaches including describing the array as a collection of logical sections.

One or more tool for setting an “on” position for placement of one or more solar modules within the roof grid and/or for setting an “off” position for removal of the one or more solar modules within the roof grid may be provided. In one example, a single tool may be useful for setting “on” and “off” positions for the solar modules. In another example, a separate selection tool may be provided for setting an “on” position, and a separate de-selection tool may be provided for setting an “off” position. Any number of tools may be provided for setting “on” and/or “off” positions.

Alternatively, “on” and “off” positions may be determined according to one or more imported file. The imported file may be a computer aided design (CAD) file, such as, but not limited to, AutoCAD, Solidworks, Solid Edge, TurboCAD, VariCAD, Advance Design, ArchiCAD, or Revit. The imported file may be any other graphics related file including but not limited to drawing programs, design programs, photo programs. The imported file may comprise data representative of one or more image. The image may be representative of a layout of one or more solar modules. The image may be representative of a surface upon which one or more solar modules are to be laid out (e.g., roof, wall, structure, ground). In one example, the imported file may include data or an image of a roof (or other surface) upon which one or more solar modules will be laid out. The image and/or data associated with the image may include one or more dimensions for the solar modules or the surface upon which the solar modules are to be laid out. Based on the image, a tool may select placement of one or more solar modules. The placement selection may include determining whether a position for a solar module is on or off. The placement selection may also include the number of solar modules, the locations of the solar modules, and/or the connections between solar modules.

In some embodiments, one or more solar module arrangement may be exported to a program. In some embodiments, one or more solar module arrangement may be exported as a CAD file or any other image file. The solar module arrangement may be exported to a CAD program, graphics/image program, or another type of external program. In some embodiments, the exported file may include information such as positions of individual solar modules (including selected or deselected solar modules), dimensions, ballasting requirements, expected loads, costs, components, or any other information described herein. The exported file may include images of the positions of solar modules and/or any other information described elsewhere herein.

For larger arrays, the system may provide the ability to multi-select a range of cells to turn an entire grid or an entire section of a grid on or off. FIG. 3 illustrates use of a multiple module selection tool 301. By using the multiple selection tool 301, a user or operator may click and drag a pointer to select multiple modules at the same time 302 to turn more than one module on or off. FIG. 4 illustrates the result of the user's selection in FIG. 3, resulting in multiple modules being turned “on.” In FIG. 5, a multiple module de-selection tool 501 may allow an operator to turn “off” multiple modules at the same time. FIG. 6 illustrates the result of the multiple module de-selection of FIG. 5.

By using this graphical interface, the user or operator may select module placements in a graphical representation. The user may drag and highlight multiple module placements in an efficient manner. As a result, a grid of possible module locations is created.

In addition to the layout of the array, the operator may also provide certain site parameters to the configuration system. For example, wind speed, exposure category, building height, module dimensions, importance factor, and other factors may be provided. Referring to FIG. 7, site details may include installation site parameters (building height, least horizontal roof distance, exposure, wind speed, ground snow load, importance factor, ballast block weight, etc.) and module parameters (width, length, thickness, weight, power, array style, etc.). In addition, various quotation details may be provided including a quotation number, name of person/entity providing the quotation, revision version number, date, company, contact name, company address, contact phone, contact email, project name, project address, module manufacturer, module model, etc.

From the information and data inputted and the array specification as entered by the user using the graphical interface, the system may calculate a complete bill of materials, customer pricing, ballasting requirements and overall roof loads for projects, using the project specific parameters and array configuration inputs. In particular, the amount of weight needed to ensure that the system does not move or lift up given expected wind and other loads may be easily calculated.

Position

FIG. 8 illustrates an example of the array specification as entered by the user as described above. The array specification as shown in FIG. 8, as entered by the user, may be uploaded to a server for processing. Referring to FIG. 9, a layout with position determinations is shown. For each “on” cell (or selected cell), the server may examine its north and south neighbors. If a cell does not have another “on” cell immediately to its north, then it is flagged as a North cell (“N”). If a cell does not have another “on” cell immediately to its south, then it is flagged as a South cell (“S”). Cells that are neither North nor South are flagged as Internal cells (“I”).

Load Sharing

In FIG. 10, the load sharing for the array is determined. When calculating load sharing, considerations of whether the hardware used allows adjacent cells to stiffen each other (for example, if both have deflectors attached and those deflectors connect to each other) may be made. If the hardware does not allow mutual stiffening, then the cell may be treated as if it had no neighbors and its neighbor counts may be set to 0.

If the hardware allows cells to mutually stiffen, then if a cell (“c”) has a cell to its east (“e”), then (c.left_neighbors=e.left_neighbors+1) and (c.right_neighbors=e.right_neighbors−1). Otherwise, (c.left_neighbors=0). Starting with the next cell to the west (“w”), active cells directly connected may be counted while moving west. The count may be stopped as soon as an empty cell or the edge of the grid is hit (“right_neighbors”). Then, values may be set such that c.right_neighbors=right_neighbors. The results of such load sharing calculations are shown in FIG.

Tray Weight Calculation

Once a cell has been classified with position and load sharing values, the weight that the cell requires may be referenced from a table calculated based on the environmental conditions such as wind speed, snow load, exposure, tilt angle, importance factor, building height, etc. from a target sight. FIG. 11 illustrates an example of the weight requirements that have been determined for various cells. For example, a cell that is north and shares with 3 others may require a 175 pound load (“c.weight”).

If a cell is “on” all trays attached to the cell will need to be present and weighted. Further, for all the attached trays (“t”), each tray (“t”) is set to “on” and t.weight=max (c.weight, t.weight). As shown in FIG. 12, an example of the weight per tray calculation is illustrated. As shown in FIG. 12, the system has placed trays at the corners between cells, but other geometries are also possible. For example, trays may be placed at the north, south, east or west sides, there may be two trays placed per cell, or a single central tray per cell. Trays that are attached to multiple “on” cells may have their weight set multiple times, but will end with their weight set to the heaviest weight required by any of the cells to which they are attached. As shown in FIG. 12, the trays with the actual weight required at that point can be provided to an installer, such that the installer can understand how to construct the system appropriately and to facilitate such installation.

Alternatively, however, since the weight used to hold down trays in ballast roof mount systems may be provided by cement blocks that can be deployed in quarter, half and full block chunks, the system may also display a graphical map of the weight requirements converted into units of blocks as well, as illustrated in FIG. 13.

In some embodiments, the amount of ballast and/or weight required for each tray of a solar module may be calculated. The amount of ballast and/or weight for each tray may be displayed on a graphical user interface. The ballasting requirements may be displayed on a roof grid representing a roof layout and/or other graphical display. For instance, a numerical value for the ballasting requirements (e.g., in weight or in number of ballast chunks) may be displayed in a graphical representation of a tray for one or more solar modules that may illustrate a solar mount system.

Other Alternative Classifications, Calculations and Categories

In addition, in another embodiment, as shown in FIG. 14, the system may classify the modules uploaded to the server from the graphical interface input into three categories (“Categories”). The Categories may be either (1) northern two rows of an array (“Northern Row”), (2) southern-most row of an array (“Southern Row”), or (3) all other modules that are not classified as Northern Row or Southern Row (“Internal Row”).

The system may also separate the arrays into various arrays that contain the maximum number of modules from east to west but do not contain a row with an east or west edge that is adjacent to another array (“Subarrays”). In other words, the system will not define any Subarrays that connect to another Subarray on its east or west edge. For example, in defining a Subarray, the system may start from the northwest corner of a particular Subarray, and then select the maximum number of columns (or modules) east, to the northeast corner of that Subarray. This selection may define the Northern Row of that Subarray. The system may then select the maximum number of rows south of that Northern Row that do not connect to another Subarray on its east or west edge, and this will define that Subarray.

As shown in FIG. 15, samples of various Subarray definitions are shown. Each single continuous east to west row in a subarray with the same module Classification is a “Section.” For example, Subarray 2 in FIG. 15 has two Northern Row Sections, four Internal Row Sections, and one Southern Row Section. Subarray 8 in FIG. 15 has only two Internal Row Sections, zero Northern Row Sections, and zero Southern Row Sections.

In addition to defining the Internal Row Sections per Subarray, the system may also calculate how many of the Internal Row Sections are connected to a Northern Row or Southern Row on an east or west edge. In other words, if an Internal Row Section is adjacent to a Northern Row or Southern Row on its east or west edge, then that would be an “Internal Row Edge Condition.” For example, Subarray 2 of FIG. 15 has four Internal Row Sections with three east or west edges connected to a Northern or Southern Row. Therefore, Subarray 2 has three Internal Row Edge Conditions. As another example, Subarray 9 of FIG. 15 has only two Internal Row Sections but zero east or west edges connected to a Northern or Southern Row. Therefore, Subarray 8 has zero Internal Row Edge Conditions.

Further, the system may also calculate “Southern Row Edge Conditions” which are Southern Row Sections that are connected to a Northern Row on its east or west edge. In other words, if a Southern Row Section is adjacent to a Northern Row (not an Internal Row) on its east or west edge then that would be a “Southern Row Edge Condition.” For example, Subarray 4 in FIG. 15 has one Southern Row Section with one east or west edge connected to a Northern Row module. Therefore, Subarray 4 has one Southern Row Edge Condition.

From the graphical entries of modules in the array, the system may calculate the number of Northern Row Modules, Southern Row Modules, and Internal Row Modules for each Subarray. Further, the system may also calculate how many rows of modules have at least one Northern Row Module but less than six modules total (a “Special Case Subarray”). In other words, a Subarray Section that has between one and five modules in a row and contains at least one Northern Row Module would be considered a Special Case Subarray.

Special considerations may apply if the Subarrays are Special Case Subarrays. As shown in FIG. 16, different ballast may be required for these special cases. The Special Case North Row Module Classification table shows how the ballasting requirements may be defined for certain conditions. For example, if a Special Case Subarray has three modules total, then the total Northern Row Modules in that Special Case may be tagged with one classification, whereas a Special Case Subarray with five modules total may be tagged with a different classification.

Various totals may be calculated, such as (1) the total number of modules on the northern edge of an array; (2) the total number of modules on the western edge of an array; (3) the total number of modules on the eastern edge of an array; (4) the total number of modules on the southern edge of an array; (5) the total number of Northern Row Modules on the east or west edge; and (6) the total number of Southern Trays not classified as a Southern Tray. With respect to the totals in #1-5, these refer to the modules that are on the outside edge of an array. The total number of modules would refer to all Subarrays including Special Case Subarrays. For #6, the total would be the number of Northern Row Module trays on a southern edge of an array, which includes noting the ballasting difference between Special Case Northern Row Modules and just standard Northern Row Modules on a southern edge. For example, referring to FIG. 16, Special Case Subarray #4 has five modules total and therefore has four total Northern Row Modules trays and therefore would be considered in the “5-E/W Connect” classification of the Tray Replacement Classification table as shown in FIG. 17.

The system may also take into account whether additional components or ballasting is needed for special circumstances or for extra parts. For example, additional tray sets, mid clamp assemblies, end clamp assemblies, deflectors, wire straps, modules, grounding lugs, or other components may be included. The system may additionally take into account whether there is a setback distance required, as shown in FIG. 18.

For instance, FIG. 19 illustrates forces exerted on the modules due to wind and how those may manifest at low sides (A) and high sides (B) of the ballast trays.
